The Portsmouth Earthworks are a large prehistoric mound complex constructed by the Native American Adena and Ohio Hopewell cultures of eastern North America (100 BCE to 500 CE). [2] The site was one of the largest earthwork ceremonial centers constructed by the Hopewell and is located at the confluence of the Scioto and Ohio Rivers,in present-day Ohio.
The majority of the mound complex site is now covered by the city of Portsmouth in Scioto County,Ohio. [2] Several individual sections of the complex have been included on the National Register of Historic Places.
Originally,the Portsmouth Earthworks consisted of three sections extending over twenty miles of the Ohio River valley,crossing from Ohio to Kentucky in several places. It was surveyed and mapped by E. G. Squier in 1847 for inclusion in the seminal archaeological and anthrolopological work Ancient Monuments of the Mississippi Valley . [3]
The northernmost section was made up of a number of circular enclosures,two large horseshoe-shaped enclosures,and three sets of parallel-walled roads leading away in different directions. One set of walled roads extends across the Ohio River into South Portsmouth,Kentucky to the southwest to Portsmouth Earthworks,Group A. Another set of walled roads lead to the southeast where it also crossed the Ohio River and lead to Portsmouth Earthworks,Group C. [3] The third set of walled roads lead to the northwest for an undetermined distance,and may point to Tremper Mound and Works,some 5 miles away. The City of Portsmouth maintains a public park which includes one of the remaining horseshoe-shaped enclosures,known as Mound Park,it is the only publicly accessible part of the complex. [2] Under the name Horseshoe Mound it was listed on the National Register of Historic Places in 1974. [2]
In 2019 two independent scholars proposed that the Group B mounds represent part of an eight-mile-long female effigy mound,which the authors propose depicts "The Woman Who Fell from the Sky," a Native American myth about human origins found among the indigenous peoples of North America. [4] If true,this would make it the longest effigy mound known,although much of the structure was destroyed by the city of Portsmouth. [5] The authors link the mounds to the story of He-nau-ee,as told by the Meskwaki Indians,possible descendants of the Hopewell mound builders. Other archeologists have cast doubt on the theory. [6]
Also known as the Old Fort Earthworks (15Gp1) it is a series of rectangular enclosures near South Portsmouth in Greenup County,Kentucky. Group A is a large square enclosure with two series of parallel walls extending from the northeast and southwest corners. The Old Fort Earthworks consist of several sites,including the Old Fort Earthworks (15Gp1),Mays Mound (15Gp16),Hicks Mound (15Gp265),Stephenson Mound (15Lw139),and several other unnamed mounds and enclosures. It is also the location of Lower Shawneetown,a protohistoric/historic Fort Ancient and Shawnee settlement and colonial trading post which are all part of the Lower Shawneetown Archeological District, [7] along with the Thompson and Hansen sites
Group C was a large series of concentric circles surrounding a high central conical mound. This section of the earthworks is located in Greenup County,Kentucky several miles to the east of South Shore,but connected to Group B by a causeway that ran down to the Ohio River.
Located to the west or downriver of Group C is the Biggs site (15Gp8) or Portsmouth Earthworks Group D. Biggs was an Adena culture circular causewayed embankment 5 feet (1.5 m) high by 30 feet (9.1 m) wide encircling a ditch 6 feet (1.8 m) deep and 25 feet (7.6 m) across. They encompassed an area 90 feet (27 m) in diameter. In the center of the ditch was a conical tumulus 8 feet (2.4 m) high and 40 feet (12 m) in diameter. It was not only mapped by Squier and Davis,they also included a small illustration of the feature. [8]
The Hopewell tradition,also called the Hopewell culture and Hopewellian exchange,describes a network of precontact Native American cultures that flourished in settlements along rivers in the northeastern and midwestern Eastern Woodlands from 100 BCE to 500 CE,in the Middle Woodland period. The Hopewell tradition was not a single culture or society but a widely dispersed set of populations connected by a common network of trade routes.
The Great Serpent Mound is a 1,348-foot-long (411 m),three-foot-high prehistoric effigy mound located in Peebles,Ohio. It was built on what is known as the Serpent Mound crater plateau,running along the Ohio Brush Creek in Adams County,Ohio. The mound is the largest serpent effigy in the world.
The Adena culture was a Pre-Columbian Native American culture that existed from 500 BCE to 100 CE,in a time known as the Early Woodland period. The Adena culture refers to what were probably a number of related Native American societies sharing a burial complex and ceremonial system. The Adena culture was centered on the location of the modern state of Ohio,but also extended into contiguous areas of northern Kentucky,eastern Indiana,West Virginia,and parts of extreme western Pennsylvania.
Hopewell Culture National Historical Park is a United States national historical park with earthworks and burial mounds from the Hopewell culture,indigenous peoples who flourished from about 200 BC to AD 500. The park is composed of six separate sites in Ross County,Ohio,including the former Mound City Group National Monument. The park includes archaeological resources of the Hopewell culture. It is administered by the United States Department of the Interior's National Park Service.
Ancient Monuments of the Mississippi Valley (1848) by the Americans Ephraim George Squier and Edwin Hamilton Davis is a landmark in American scientific research,the study of the prehistoric indigenous mound builders of North America,and the early development of archaeology as a scientific discipline. Published in 1848,it was the Smithsonian Institution's first publication and the first volume in its Contributions to Knowledge series. The book had 306 pages,48 lithographed maps and plates,and 207 wood engravings. The book was reissued in 1998 in paperback,with an introduction by David J. Meltzer,professor of anthropology at Southern Methodist University.
The Newark Earthworks in Newark and Heath,Ohio,consist of three sections of preserved earthworks:the Great Circle Earthworks,the Octagon Earthworks,and the Wright Earthworks. This complex,built by the Hopewell culture between 100 BCE and 400 CE,contains the largest earthen enclosures in the world,and was about 3,000 acres in total extent. Less than 10 percent of the total site has been preserved since European-American settlement;this area contains a total of 206 acres (83 ha). Newark's Octagon and Great Circle Earthworks are managed by the Ohio History Connection. A designated National Historic Landmark,in 2006 the Newark Earthworks was also designated as the "official prehistoric monument of the State of Ohio."
The Hopeton Earthworks are an Ohio Hopewell culture archaeological site consisting of mounds and earthwork enclosures. It is located on the eastern bank of the Scioto River just north of Chillicothe in Ross County,Ohio,about 1 mile (1.6 km) east of the Mound City Group and Shriver Circle on a terrace of the Scioto River. The site is a detached portion of the Hopewell Culture National Historic Park,along with the Mound City Group,Hopewell Mound Group,Seip Earthworks,Spruce Hill Earthworks and the High Bank Works. The site is open to the public.
The Tremper Mound and Works are a Hopewell earthen enclosure and large,irregularly shaped mound. The site is located in Scioto County,Ohio,about five miles northwest of Portsmouth,Ohio,on the second terrace floodplain overlooking the Scioto River. It was listed on the National Register of Historic Places in 1972.
Prehistory of Ohio provides an overview of the activities that occurred prior to Ohio's recorded history. The ancient hunters,Paleo-Indians,descended from humans that crossed the Bering Strait. There is evidence of Paleo-Indians in Ohio,who were hunter-gatherers that ranged widely over land to hunt large game. For instance,mastodon bones were found at the Burning Tree Mastodon site that showed that it had been butchered. Clovis points have been found that indicate interaction with other groups and hunted large game. The Paleo Crossing site and Nobles Pond site provide evidence that groups interacted with one another. The Paleo-Indian's diet included fish,small game,and nuts and berries that gathered. They lived in simple shelters made of wood and bark or hides. Canoes were created by digging out trees with granite axes.
The Mount Horeb Earthworks Complex is an Adena culture group of earthworks in Lexington,Kentucky. It consists of two major components,the Mount Horeb Site 1 and the Peter Village enclosure,and several smaller features including the Grimes Village site,Tarleton Mound,and Fisher Mound.
